FIREWORKS-TORCH.

SPECIFICATION forming part of Letters Patent No. 494,438, dated March28, 1893.

Application filed January 16, 1892. Serial No. 418,268. (No model.)

To all whom it may concern:

Be it known that I, THOMAS M. PIERCE, of Concord, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Fireworks- Torches, of which the followingisafull, clear, and exact description.

This invention has for its object the supply of air to the center of theflame of the burning composition of a fireworks torch, to produce notonly a better flame but to lessen the quantity of smoke generated by theburning material, and the invention consists of a fireworks torchprovided with a central longitudinal passage extending through thelength of the torch and provided with an opening or openings at the sidenear or at the lower end, or extending through the bottom of the torchand handle connected thereto, all substantially as hereinafter fullydescribed reference being had to the accompanying sheet of drawings inwhich is illustrated a fireworks torch constructed in accordance withthis invention.

Figure 1, being a side view; Figs. 2 and 3, central vertical sections;Figs. at and 5, cross sections on lines 4-4, and 5-5, respectively, Fig.2; Fig. 6, a cross section on line 6-6, Fig. 3.

In the drawings A, represents a fireworks torch of which B is a casingor tube of paper or other suitable material, C ahandle inserted andsecured in the lower end of the casing or tube, which handle can be ofwood or any suitable material and D is the fireworks composition, all asusual in the manufacture of fireworks and needing no more particulardescription herein except as to the present invention.

Centrally longitudinally within the tube or casing B, is a tube E, ofpaper or any suitable material which extends the length of the tube orcasing B, and is secured at its lower end in the handle 0, which leavesa vertical annular chamber between it and the outer casing or tube, inwhich annular chamber is placed the fireworks composition D. Below thetube E is a horizontal passage J, which extends transversely through thehandle and communicates with the vertical passage H, of the central tubeE.

In Fig. 3, the transverse passage J, is dispensed with and a centralvertical passage K, made through the length of the handle communicatingwith the passage H, of the central tube.

In the use of the torch it is held in the hand by the handle, orsupported in the ground and ignited at the upper end L, in the usualmanner, and as the composition burns at the upper end a draft is createdup through its central passage H, and through the body of the flame, theair passing in at the ends P of the transverse passage or at the lowerend M, of the passage K in the handle,supplying air to the center of theflame in such quantity that the flame will vbe much brighter and morebrilliant and freer of smoke.

The transverse air passage can be made in the casing itself in lieu ofin the handle, but it is preferable to have the handle and such airpassage in it, also such passage need open only to one side but it ispreferable to have the passage extend across making two inlets for air,which is advantageous. The central tube also gives additional strengthto the torch.

Having thus described my invention, what I claim 'is 1. A fireworkstorch, composed of an outer casing, a longitudinal central tube, anannular chamber between the two tubes for the fireworks composition, thecentral tube having an air passage through it and opening to the outsideof the torch at or near its lower end for the purpose specified.

2. A fireworks torch, composed of an outer casing, a longitudinalcentral tube, an annular chamber between the two tubes for the fireworkscomposition, the central tube having an air passage through it and atransverse air passage having an outlet at the side of the torch at ornear its lower end and communicating with the central tube air passagefor the purpose specified.

3. A fireworks torch, composed of an outer casing, a longitudinalcentral tube, an air passage through the tube an annular chamber betweenthe two tubes for the fireworks composition, and a transverse airpassage extending from one side to the other of the torch having anoutlet on each side of the torch at or near its lower end and centrallyconnected to and communicating with the central tube air passage for thepurpose specified.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing 19 witnesses.

THOMAS M. PIERCE.
